I did a search and couldn't find any info on this. Has anyone experienced a high rpm(~800) after changing out the spark plugs? I have no check engine light on and found no leaks. It's been 2 days since it started happening. Thanks for any help!

 

try resetting the ECM, then running the idle vol learn, and throttle stop learn (if you have a vq35)

 

I've done all that already and still get the high rpm. Anyone else?
